So I installed it on my mac to get started. I was wondering if there is some way to make non-vertical gridlines in Sage.
For example, I used
show(L,gridlines=True)
for some graphics object L. Now I want to rotate just the y axis gridline by 30 degrees. How can I do it?

http://ask.sagemath.org/question/8159/angular-gridlines-in-sage-plot/?answer=12438#post-id-12438I don't know any option to do that at once, but you can use something like:
var('x y')
line = 2*x + y
p = plot(...)
grid = sum(implicit_plot(line+k,...) for k in srange(-1,1,0.2))
(p + grid).show()
to add the grid manually.
